could affect life on land AND in water
What happens to the amount of
pollution as you travel up a food chain?
Why is this significant?
What is the difference between Cap

Objectives
By the end of today, all SWBAT…
• Describe the difference between
conservation and preservation models
• Explain the advantages and
disadvantages of the zoo model
The wild areas are disappearing
And the animals are going extinct…
So, what do
we do…?
2 lines of thinking…
Conserve = to use
wisely
Preserve = to keep safe,
not to use
Conservation vs. Preservation
Conservation
Preservation
Goal
Save species
Save species
Definition
Humans protect species
while benefitting from
them
“Hands on”
Saving species in their
original state
“Hands off”
Humans?
Yes
No
Advantages
Humans benefit
Humans don’t impact
animals
Disadvantages
Animals don’t live a
“regular life”
Humans don’t benefit
Hard to get money to fund
Misuse of
Resources
Conservation
Preservation

The Zoo Model: Good
or Bad for our
Animals?
Key Point #2

Zoos have many purposes
 Provide
entertainment
 Conserve species
 Educate people about animals
Pros (+)



Teach children to value animals
Keep animals safe
Breeding programs increase
population sizes
Cons (-)




No zoo has saved a species from extinction
Poor treatment of animals
Take out of native environment
Animals develop odd behavior
Debate…FOR or AGAINST zoos
A California zoo decided to aid in
conservation of the animal by adding two
polar bears to its exhibit. Unfortunately, the
climate is much different in California than the
arctic tundra.
 As a result, the polar bears react oddly to the
temperature difference. The two bears swim
laps in the small pool in their exhibit all day to
keep cool. Additionally, the pool is not large
enough for both polar bears at the same time.

Debate…FOR or AGAINST zoos
Unfortunately, some zoos in third-world
countries do not have strict laws regarding
animal care and do not properly care for their
animals.
 The Ragunan Zoo in Indonesia received many
complaints that there was trash in many of the
animal exhibits. Shortly after these complaints,
an orangutan died from a plastic bag that got
stuck in its digestive tract.

The Palm Beach Zoo spends thousands of
dollars every year in breeding programs. Five
jaguar cubs have been born at this zoo.
Additionally, the jaguar is a solitary animal
(lives alone). Therefore, populations of jaguars
require atleast 3 acres of space (a large
amount) to survive in the wild. However, the
jaguar exhibit in the Palm Beach zoo places
two jaguars in an area of ½ acre.
